Abstract
Electrical activity is the basis of human life activities. Regulating electrical activity changes the excited and inhibited states of cells, tissues and organs to treat diseases. Nanogenerators are the new type of energy conversion device that convert low-frequency mechanical energy into electrical energy. In addition, it has gained the attention of researchers because of the flexibility, spinnability, high-output voltage, structural and material diversity. We employed nanogenerators to efficiently convert the mechanical energy of human motion into electrical energy and supply power to electrical stimulation devices and biosensors. Then, we developed self-powered electronic medical devices and medical sensors to carry out more systematic research work. For example, the power generated from the heartbeat can be used to drive the cardiac pacemaker to work for a long time, construct symbiotic cardiac pacemaker, as well as complete the research on improving heart rate and treating arrhythmia in the large animal experiments for the first time. Degradable self-powered electrical stimulation devices are used to regulate the growth direction of nerve cells, enhance intercellular integration and regulation of cardiomyocytes, promote osteoblasts proliferation and differentiation, accelerate skin wound healing. Besides, the devices can be completely absorbed by the body after the disease treatment. There are researches on self-powered cardiovascular biosensors that can realize minimally invasive implantation and have good biocompatibility. These researches focus on self-powered electronic medical devices and electrical stimulation therapy, and have important potential to be transformed into electronic medical devices and medical sensors for clinic treatment.
